SPECIFICATION forming part of Letters Patent No. 716,369, dated December 23, 1902. Application filed August 12, 1902. Serial No. 119,404:- (No model.)

To all 107110772 it may concern:

Be it known that I, BENJAMIN F. BINNIX, a

citizen of the United States, residing at Seabrook, in the county of Prince George and State of Maryland, have invented certain new and useful Improvements in Smoke-Consuming Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to improvements more especially in boiler-furnaces. It has for its object, primarily, to effectively consume all smoke or products of combustion previousto the discharge of the same from the furnace and smoke-stack, also to promote combustion and to otherwise improve the furnace generally.

It consists of the combination and arrangement of parts substantially as hereinafter more fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, which form part of this specification, Figure 1 is a vertical longitudinal section thereof. Fig. 2 is a section taken on the line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a section taken on the line 3 3 of the same figure looking in the direction of the second arrow. Fig. i is a side elevation of said invention. Fig. 5 is a broken plan view thereof, and Fig. 6 is a broken rear elevation of the same.

It will be understood that latitude is allowed herein as to structural and other detai1s,as they may be changed as circumstances suggest without departing from the spirit of my invention and said invention remain intact and be protected. I

In carrying into effect my invention I erect an inclosure or structure 1, as usual in general outlines, of masonry to provide for inclosing or housing the boiler 2 and forming the fire or grate chamber 3 and ash-pit 4. Said inclosure or structure has also arranged orbuilt therein bridge-walls 5 5*, respectively, one forming the back wall of the fire or grate chamber. The other bridge-wall subdivides the space of said inclosure under the boiler between the first-referred-to bridge-wall and the back or rear walls of said inclosure into or structure 1 for commingling with the prodnets of combustion, as further presently explained, for the effective consumption of smoke, 850., previous to the same'leaving the furnace. Each chamber 7,it will be observed, while restricted in area in one direction between the front and rear portions of a bridgewall extends in another direction for a little less than half of its depth the entire Width or cross-sectional area of the interior of the inclosure 1, providing an extended air-containing space or capacity therefor. The remaining upper portion of each chamber 7 extends upwardly to the top of said inclosure in contracted flue-like form, as 7 upon each side or laterally of the boiler, the same communicating with the external air through openings in said inclosuretop. Said openings are adapted to be controlled according to the amount of air required to be passed therethrough by valves 8, each two of which is connected to and adapted to be actuated or manipulated by a common handled or actuating rod or stem 8, axially mounted or pivoted in suitable manner upon said inclosure-top, as shown in Figs. 1 and 5. Said bridge-wall chambers 7 are provided with air inlets or openings 7 in their surfaces about opposite the lower surface of the boiler 2, said bridge-wall surfaces being removed short distances from said boiler-surface to provide passages 9 therebetween for the passage of the products of combustion and the commingling therewith of the air-jets entering saidpassages and finally the furnace or combustion-chambers 6 6*, as they do, through said air inlets or openings 7 for the purpose aforesaid. Said bridge-wall surfaces, forming the bottoms and lateral portions of the passages 9, are adapted to have the maximum air-inlet area to provide for the requisite commingling of the air and products of combustion to promote the consumption of the latter. Said bridge wall chambers 7 in addition to extending clear down to the bottom of the inclosure 1 communicate with each other via passages or fines 10, one of said chambers communicating with the ash pit or chamber 4 by means of openings or passages 10 in alinement with the passage or flue 10, delivering hot air therethrough into said bridge-wall chambers, as will be appreciated, to further aid the gas or smoke consuming process. Said air openings or inlets are adapted to be controlled by a common valve or plate 11, actuated by an axially pivoted or hung rod or stem 11. Communication is also effected between the external air and said bridge-wall chamber 7 laterally via air inlets or openings 12, controlled by valves or plates 12 carried and actuated by an axially hung or pivoted rod or stem 12*, suitably adapted for convenient manipulation. Suitable means, as preferably disclosed in Figs. 3 and 4, may be employed for propping or retaining said valves open.

In the rear end of the inclosure or structure 1 is also, preferably, an air chamber or flue 13, having communication with the external air at its upper end near the top of said inclosure through an opening 15, controlled by a valve or plate 13, similarly hung or actuated as those above referred to. Said fine or chamber also extending preferably the entire Width of the inclosure-chamber communicates at its lower end by way of passages 10 with the rear bridge-wall chamber 7, said passages preferably alining with and corresponding to the passages 10. Said passages 10" open out through the rear wall of the inclosure 1, as at 10, to likewise receive air at that point, which air, with the air from the chamber or flue 13, enters the rear bridgewall chamber 7. Said air is delivered by the way of the air inlets or openings 7 of said chamber and the rear combustion-passage 9 finally through the secondary or supplemental combustion-chambers, respectively, uniting with any as yet unconsumed products of combustion or gases and resulting in the effectual consumption of said products or smoke, as has been found to be the case by practical demonstration in the use of my furnace. Said openings or inlets 10 are controlled as to the quantity of air to be admitted therethrough by a common valve or plate 14, carried by a suitably or axially hung or pivoted rod or stem 14, adapted to be conveniently actuated by hand.

Having thus fully described my invention, what I claim is 1. A boiler-furnace provided with a plurality of bridge-walls having air-chambers therein, means for supplying hot air thereto from the ash-pit, means for discharging air in separate jets or streams at substantially a right angle to the products of combustion passing from the furnace,a combustion-chamber between, and whose ends are formed by said bridge-walls, passages or fines under said combustion chamber connecting the airchambers in the bridge-walls, and means for regulating the supply of air to the chambers in the bridge-walls.

2. A boiler-furnace provided with a plurality of bridge-walls having air-chambers therein, means for supplying hot air thereto from the ash-pit, means for discharging air in separate jets or streams at substantially a right angle to the products of combustion passing from the furnace, a combustion-chamber between, and whose ends are formed by said bridge-walls and of a depth approximately the depth of the air-chambers, passages orfiues under said combustion-chamber connecting the air-chambers in the bridgewalls, and means for regulating the supply of air to the chambers in the bridge-walls.

3. A boiler-furnace provided with a plurality of bridge-walls having air-chambers therein, means for supplying hot air thereto from the ash-pit, means for discharging air from said chambers in separate streams to commingle with the products of combustion passing from the furnace, a combustion-chamber between, and whose walls are formed by said bridge walls, passages or fines under said combustion-chamber connecting the airchambers in the bridge-walls, and means for regulating the supply of air to the chambers in the bridge-walls.
